i am looking for cq.foundation-main client library path. I would like to disable granite.jquery client lib on aem 6.3
Thanks.
DISCLAIMER: I would not disable granite.jquery clientlib as it is a dependency for many other clientlibs and might break the UI in your AEM instance. Do this at your own risk.
here is the answer to your question:
to find the location of any clientlib, you can go to: http://localhost:4502/libs/granite/ui/content/dumplibs.html
then search for the clientlib category, in your case: cq.foundation-main
and the path will be listed.
on my 6.3 instances, that path is /etc/clientlibs/foundation/main
